Decision Log for Family Caregiving is a startup idea for family caregivers and adult children. The primary caregiver keeps getting directions from relatives who aren't involved day to day but feel entitled to criticize. There's no shared record of what was decided and why. A thread in r/CaregiverSupport drew 88 upvotes and 40 comments between Sep 14, 2026 – Oct 14, 2026. People get by with CaringBridge, Lotsa Helping Hands, and Group chats, and that still leaves this job open. Hotness is 3.50, Hot. Strong pain. Some willingness to pay. The thread drew 88 upvotes and 40 comments. Only clumsy or enterprise-only options. A 1-2 week mvp. A first version is weekend-easy, about 2 weeks, priced under $10 a month and charged as a free tier and a paid upgrade. The pain, the source, the alternatives, the scope notes, and the questions on this page are free to read and free to build from. The agent starter prompt is the paid part. The first slice is on the page. One credit unlocks the rest, to paste into a coding agent, download as Markdown, or send as a private link.

A way through
A family care coordination app with a decision log and rationale (not just tasks) that ends repeat arguments by linking to the decision already made and explained.
MVP scope
The first version, in 2 weeks.
- 00 Goal
The one job
A shared record of care decisions and the reasons behind them, so relatives stop relitigating every choice.
- 01 Week 1
The core
Record each care decision with the reason behind it, not just the task.
- 02 Week 1
The follow-through
Link relatives to the decision already made and explained, instead of reopening it.
- 03 Week 2
How it ships
As a web app that opens in any browser, with nothing to install. AI helps, but the core job works without it.

Market size · estimate
How big this could get
A bottom-up estimate for Decision Log for Family Caregiving: real customer counts × a realistic price. Not a forecast.
$624M a year
13M families · 20% of US family caregivers
$187M a year
3.9M families · online, US
$1.9M a year
39,000 families · 1% of the reachable segment in three years
What that means
39,000 families at $4/mo = $1.9M ARR
Medium confidenceHow we estimated this
- Base: 63,000,000 US family caregivers.
- Has the problem: 20% (assume 1 in 5 coordinate care with siblings).
- Revenue per familie: $48 per year ($4/mo).
- Reachable: 30% (online, US).
- Three-year capture: 1% of the reachable segment.
TAM = customers with the problem × revenue per customer. SAM = the part an early product can reach. SOM = a conservative three-year share of SAM. Bars use a log scale. Shares marked “assume” are our judgment, not measured.

Is this idea already taken?
People already use CaringBridge, Lotsa Helping Hands, Group chats. Those options do not do the job in the solution above. The idea is free to build. Nothing here is an exclusive claim.
How hard is a first version?
Weekend-easy. A tight MVP is about 2 weeks (2 weeks), assuming the regulated or partner-gated parts are stubbed. The paid prompt turns that into tasks.
Who would pay, and how?
The audience is family caregivers and adult children. Charge a free tier and a paid upgrade, and test a price under $10 a month. Willingness to pay is one input to Hotness, not a promise that someone will buy.
Can I use the evidence?
Yes. Build the product. The thread title is a short excerpt with a link, not a quote we are putting in someone's mouth. Exact post dates and verbatim lines are added only after a manual check. Ideas are suggestions, not medical, legal, or financial advice.
